Back a couple of days, I finished reading another book, this being Osprey Fortress #8: Defenses of Pearl Harbor and Oahu 1907 – 50 the gist of which is pretty obvious in the title. This was an early title in this series of books and I'm sure that they expected it to be pretty popular, but it didn't really spark much interest in me. I guess I just looked at it as an example of failure, since these defenses didn't protect the Pacific Fleet from Japanese carrier aircraft. Anyway, there it is.
